'lO AliL WHOM 11 'MAY CONCERN:

Be it known that I, C. L. EAs't'llAu, ot' lihodes Point, in the countyof McDonough, and State of Illinois, lHlVc invented certain new anduseful improvements in Gang-Ploughs; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, making part of thisspecificution, and to the letters of refereneemarked thereon, likeletters indicating like parts wherever they occur.

To enable others skilled in the art to construct and use my invention, Iwill proceed to describe it.

My invention consists in a novel manner of constructinggang-ploughs, bywhich they can be more easily and perfectly controlled by the ploughman,as hereinafter explained.

Figure 1 is a longitudinal vertical section taken on the line :0 n: offig 2.

Figure 2 is a top plan view of the plough complete and ready for use.

I provide an axle, A, and mount it on two wheels, and attaeha tongue,il, rigidly thereto, in any suitable manner. To the rear side of theaxle'I hinge a transverse bar, C, by'means of eye-bolts o, and to thisbar I attach rigidly a lover, I, which projects vertically upward, so asto be within reach of the driver when mounted on the seat S, there beinga curved ratchet-bar, h, bolted to theuxle, and projecting upward andbackward, and having a series of notches formed in its edge to receiveand hold the lever Z where desired. To the rear side of the bar C areattached two staples c, as shown in fig. 2, to which the front end ofthe plough-beams Bare cornected by means of clevis 2', as representedmore clearly in fig. 1. 'lwo plough-beams are used, each having aplough, P, attached, as represented in the drawings, the beams beingrigidly connected by cross-bars, as shown; The standardI of the ploughsis pivoted to the beam, and held in place by a brace, 12, having a slotor series of holes, by which the pitch of the plougbs may be adjust-edas desired. A lever, L,'having its rear. end pivoted to the rear portionof the plough-beams, extends forward of the axle and rests on a support,I), under the seat, its front end being proyided with a foot-board, it.An elbow-lever, Eis pivoted to the side of the tongue, as represented infig. 1, and its horizontal arm is connected by a link, 1, to, the frontend of lever L, there being a notched plate, 122, secured to the edge ofthe foot-board it, for holding the lever E in any desired position.

By drawing this lever E backward the front; end of level. 1 isdepressed, and this acting on the fulcrum b elevates the rear end of theplough-beams, and thus keeps the ploughs clear of the ground. By meansof the lever Z the bar C maybe tilted up or down, and thus raise orlower the plough-points at pleasure, and by means of the clevis z'theymay be set to run deep or shallow, as desired, thus giving the operatorperfect control of them.

Having thus described my invention, what I claim is- 1. The combinationof the axle A and hinged bar G, provided with the lover I, and havingthe ploughs attached thereto as described, all constructed and arrangedto operate substantially as set fort-h.

2. The combination of the lever L connect-ed to the plough-beams, andhaving afulcrum at or near the axle, with the elbow-lever E pivoted tothe tongues, or equivalent part, arranged to operate as described.
